FIRE-ENGINE HEATER.

SPECIFICATION forming part 4of Letters Patent No. 542,065, dated July 2,

Application filed March 25, 1895. Serial No. 543,067. (No inodel.)

To all whom t may concerns Beit known that I, HERBERT E. PENNEY, ofMinneapolis, Hennepin county, State of Minnesota, have invented certainnew and useful Improvements in Fire -Engine I-Ieaters, of which thefollowing is a specification.

My invention relates to lire-engine heaters, and the object I have inview is to provide a simple and convenient device to be used inconnection With the engine-boiler for keeping the water therein hot atall times While the engine is in the house and also'maintaining a highpressure of steam so that the engine will be always ready for immediateuse in case of fire.

A further object of my invention is to provide an auxiliary boiler orheater adapted to go with the engine when it is drawn out of the houseand which will be carried along with the engine when it starts withoutrequiring an attendant to disconnect the same from the furnace orheating apparatus, which operation necessarily consumes considerablevaluable time and delays/the starting of the engine.

My invention consists generally in providing a fire-engine. boiler Withan auxiliary boiler permanently attached thereto and arranged to becarried With the engine Wheuit goes out to a fire, in combination withasuitable stove or heater arranged to receive the auxiliary boiler whenthe engine is standing in the house, whereby the Water in theengineboiler will be kept circulating through the auxiliary boiler, anda high pressure of steam maintained at all times in the engine-boiler;and, further, my invention consists in various combinations andconstructions, all as hereinafter described, and particularly pointedout in the claims.

The invention will be more readily understood by reference to theaccompanying drawings, forming part of this specification, and

Figure l is aside elevation of a fire-engine with my invention appliedthereto. Fig. 2 is a side elevation of the stove, the shell or coveringtherefor being shown in vertical section. Fig. 3 is a plan View of theboilerand the stove, showing the auxiliary boiler in its normal positionover the fire, its position when the engine is in use being indicated bydotted lines. Fig/i is a vertical section of the auxiliary boiler itselfand the cover for the same whenthe engine is in use. Fig. 5 is atransverse section `on the linear tc of Fig. 4.

In the drawings, 2 represents the boiler of a fire-engine ofthe-ordinary construction as it appears when not in use in theenginehouse. At the rear of the engine and a short distance therefrom Iprovide an upright stove 3, having the smoke or outlet pipe 4, andprovided in its side nearest the engine with a vertical opening 5. Thisopening is normally closed by swinging doors 6 and is of sufficient sizeto receive the small auxiliary boiler when the engine is backed intoposition in the house.

Theauxiliary boiler comprises the hollow heads '7 and 8, the head 7having the large central opening, as shown in Fig. 5, and the head 8being provided with a central opening in its upper surface, which iscovered by a plate 9 securely fastened to the head by screws or bolts,as shown in Fig. 4. movable plate permits access to the interior of thehead to the series of tubes -or flues 10, which connect with the heads 7and 8. The opening `in the center of the head 7 permits the flames topass up between the tubes of the heater and therefore subjects the WaterHowing through the tubes to a very intense heat, so that in avery shorttime after the auxiliary boiler has been pushed back into the stove theWater in the boiler Will begin to circulate through the auxiliaryboiler, and in a short time will begin to generate steam very rapidly.The heads 7 and 8 are each provided on the side of the auxiliary boilernext to the engineboiler with openings Il and l2 to receive the pipes 13and 14,\which connect directly with the boiler of the engine, the pipe13 entering the boiler near the Water-line, While the pipe la passesthrough the boiler-shell near the bottom thereof. p

Suitable couplings 15 and 16 are provided in the pipes'l and 14, so thatwhen the engine` starts out of the house the auxiliary boiler may beswung round to the position over the fuel-box, as shown in Fig. 3, andwhen the engine is in use at the tire the auxiliary boiler may be swungaround to the This re-- IOO 4o vents the unnecessary heating of thehouse other position indicated by dotted linesinl Fig. 3, Where it Willbe entirely out of the Way when it is desired to fire the engine-boiler.

A hood or cover 17 is provided, made of suitable'material and having ahandle 18, said hood being arranged to slip down over the auxiliaryboiler as the engine starts out of the house, thereby preventing in ameasure rapid cooling ot' the iiues of the heater, and also preventingany dangerot' the firemen being burned by coming in contact therewith.The hood is also provided With a longitudinal slot Which permits it tobe slipped down over the auxiliary boiler, the pipes 13 and 14 slidingin the longitudinal slot. By grasping the handle 18 the auxiliary boilermay be swung to either of thepositions indicated by dotted linesWhenever desired. The doors 6 are provided with openings at the top andbottom, through which the pipes 13 and 14 respectively pass, and eachot' said pipes is provided with asliding sleeve or collar 19 and aspring 2O coiled about the pipe between the doors and the collar, whichupon being put under compression bythe collar 19 will hold the doorsclosed While the auxiliary boiler is in nits normal position Within thestove. The collar 19 is held from slipping on the pipe by an ordinaryset-screw.

For summer use, particularly, I provide a shell or cover 21 for thestov-e 3, as shown in Figs. 1 and 2. This covering may be made of anysuitable material and covered with asbestos or other non-conductingmaterial, if desired, and is preferably provided at its base with aseries of openings 22, through which the air circulates and carries theheat radiated from the stove up into the top of the house or into thechimney, and thereby preduring hot Weather. The casing or shell 21 isalso provided with openings on either side corresponding and registeringwith ,the doors in the stove, both the fuel door and the doors 6,heretofore described. The stove lire-pot is preferably lined up withtire-brick to aid in retaining the heat around the heater, and also toprevent the rapid burning out of the stove from the intense heat Within.

The operation of my device is as follows: The normal position of theheater when the engine is standing in the house is shown in Fig. 1. Ahot tire being maintained in the stove, the water in the boiler soonbegins to circulate through the auxiliary boiler and steam is generatedvery rapidly until it reaches the desired pressure, usually from sixtyto eighty pounds.

When an alarm ot' tire is sounded and the engine starts out of thehouse, the auxiliary boiler is drawn out of the stove as the enginepasses out and, after the hood or cover 17 is placed over the auxiliaryboiler, the Whole apparatus may be swung around over the fuel box out ofthe Way. There being a high pressure of steam already generated in theboiler,

steam and in a few moments the engine Will be ready for service again.In all other engine auxiliary boilers Where the heater is left in thehouse it is necessary to disconnect the pipes and make connections witha tank, or else leave an attendant to Watch the fire in the stove orfurnace after the departure ot' the engine, While in other devices,where the heater accompanies the engine, it has been found impossible,with the gasoline-burners usually employed, to heat the Watersufiiciently to generate steam, and for this reason the devices of thiskind have been practically Worthless.

It is obvious that the size of the auxiliary boiler may be changed atpleasure in order to increase the heating-surface, and it may be made ofvarious kinds of material Without departing from the spirit of myinvention.

Having thus described my invention, I claim as new and desire-to secureby Letters Patent- 1. In a device of the class described, thecombination with a movable steam boiler and its re box, of an auxiliaryboiler arranged outside the main boiler, but connected therewith forcirculation, and a stationary stove or heater into which said axuiliaryboiler may be inserted, and from which it may be separatedby themovement of the main boiler, substantially as described.
